What a beautiful build thread of your first DR200s howiez.

That's a good inspiration for mine in the near future.

If I would have time in the future (and a little money left over) it tickles in my fingers to build a double Lab12 loaded Titan48. I know it's a waste of efficiency per driver because you build the narrow width for each driver and have the highest costs per cab and a very heavy Titan48 but with this...

Hello Ryno, I use some of the 90° Speakons. They are a little bit more complicated to build together if you make your cables than the standard speakons. But they have the same quality. But the 90° bend only point downwards. So if you need them to point upwards you have to rotate your speakon socket ...

Hi Seth,

good luck for the process.
I think your speaker projects will wait until you're recovered

Holy moly Seth, the 36" wide T48 is really powerful (if you have a huge truck to transport the massive cab). But there shouldn't be any standard doors :lol: :lol: Yes I've built two 19" wide T39 but didn't use them outdoors yet because it's winter time you know ;) Next I will build two Oto...

Yeah, as a electrical engineer it's all about math :P You're welcome. This way it's so simple to estimate the expected SPL. A pity the dB(max) of the SPL Tool is 140 dB :lol: You gave me an idea to calculate this for all the different widths: T39W16D3012+25.77,T39W24D3012LF+23.5,T39W30D3012+21&w...

[...] +21 for one cab, subtract 6 for doubling of cabs to two, subtract another 6 for doubling cab count to four, gives me 9dB to be made up with amplification. Four cabs is 4 watts. 2.83volts/1 watt each. Double that to account for the first 3dB is 8 watts. Double that again for the next 3dB is 16...

Good job Radian ,

how are your grills holding because I can't see any screw? Magnets?

Do you know which subs you will build for your SLAs?

Where did you see that file/code option? Just added the faktor in dBs If you can go 24, do it. And use the 12's. You'll not be disappointed. At 40Hz, a single 24" is nearly twice the output of two 15" wide cabs on the same voltage (twice the power/watts). Put another way, if the driver co...

I find interesting that the difference between the T39 and T48 isn't huge if you calculate with SPLmax with the voltage limits written in the plans: T39W24D3012LF+25.77,T48W24D3012+24.9,T48W15D3012+30.9,T48W24D3015+26.5&width=650&height=250&dbmin=110&dbmax=140&fmin=20&fmax=20...

Hello Tom, this wasn't clear for me that this would make such a huge difference... Thank you very much. I know that it would be much better if I would go wider to get the most out of each driver. My initial plan was to build a double twelve but decided to build splitted for easy transportation. Beca...

A big thumbs up for you Seth, thanks so much. So I think we are one the same route for limitation and filter settings. I only would like to get help in interprating of the recommendations in the plans. What configuration did you settle on? Is it a single loaded, 19" wide (external)? Yeah I fini...

Thanks a lot Bruce.
That's real simple.

I think too that it would be safer to leave the recommended HP at 40 Hz untouched and use a 24 dB slope instead of knocking the hell out of the cabs with the lower HP and use the 48 dB slope.
I could imagine that this would sound “warmer“ too.

Thanks

Hey all, sorry that I ask a again a question about the Titan48. I finished the build of my 3012lf loaded T39 for "home usage" :P Now I would like to choose the next step for my summer rig. I've tested some tracks I'm listening and saw that a HP of 35 Hz will be better than 40 Hz. In the pl...

Bruce,

if you ever heard a BMS 4590 on a large horn as the JBL than you would understand

Do we "need" such huge horns? ... No
Are they good and sound amazing ... absolutly YES
